To (ZZZ whom it may concern.- j

Be it known that we, JACOB M. TRUBY, residing at Starke, in the countyof Bradford, and RICHARD E. FoXwoRrH, residing at Brooklyn, in thecounty of Clay, State of Florida, citizens of the United States, haveinvented a new and useful Fumigator, of which the following is aspecification.

This invention relates to fumigators; and the object in view is toprovide a device by means of which trees, plants, flowers, &c., may bethoroughly fumigated in such mannor as to destroy bugs and other insectlife without in any Way damaging or injuring the blossoms and otherparts of the plants. ,The apparatus is intended for hand use, and thedischarge end of the device .may be readily movedfroni place to placefor directing a' cur rent of smoke from the fumigator upon the blossoms,leaves, or other portions of the plants.

The detailed objects and advantages of the invention will appear in thecourse of the subjoined description.

The invention consists in a fumigator embodying certain novel featuresand details of construction and arrangement of parts, as hereinafterfully described, illustrated in the drawings, and incorporated in theclaims.

In the accompanying drawings, Figure 1 is a perspectiveview of a'fumigator complete constructed in accordance with the present invention.Fig. 2 is a vertical longitudinal section through the same, omitting thebellows. Fig. 3 is a cross-section taken through the fire-box. Fig. 4 isa detail longitudinal section showing the relation of the contracted endof the blowpipe to the discharge-nozzle.

Similar numerals of reference designate corresponding parts in all thefigures of the drawings.

The fumigator contemplated in this invention comprises a bellows l orother suitable hand device whereby a strong current of air maybedeveloped for use in connection with the fumigatin g apparatus. Thisbellows may be constructed in any usual or preferred man ner. Leadingoutward from the bellows is a blowpipe of suitable length, the extremityof which is contracted to form a conical discharge end or nipple 3. Theblowpipe 2'passes' longitudinally through the fire-box 4, which forconvenience is shown of rectangular form, but which may be constructedin any desired shape or size, according to requirements. It is, however,preferred to provide the fire-box with a flat bottom 5, upon which theapparatus may rest when out of use. The pipe 2 passes entirely throughthe fire-box, being received in openings 6 in the opposite ends thereof.

Connected to the outer end of the fire-box 4 is a conical spout ornozzle '7, the larger end of which is connected to the fire-box and theouter or reduced end of which has connected thereto a tubular extension8, adapted to receive one or inore additional lengths of pipe when theapparatus is to be used for fumigating trees of considerable height inorder that the discharge end may be carried to an elevated point. Thedischarge end of the blowpipe is located in the reduced end of thenozzle and is of slightly-smaller size, so as to leave a surroundingannular space, through which the air and smoke from the fire-box arecaused to pass by suction created by the current of air developed by theblowpipe and projected from the discharge end thereof. From theforegoing description it will be seen that the fire-box is supportedupon the blowpipe, the latter being in turn supported by the bellows.

Within the fire-box and surrounding the blowpipe 2 is a perforatedcylinder or tube 9. This perforated tube extends longitudinally theentire length'of the fire-box, being sup ported at its ends upon annularcollars or flanges 10, which project inward from the end walls of thefire-box. The diametrical size of the perforated tube is such as toleave an annular space between it and the blowpipe in order that thesmoke and products of combustion may be sucked in through the openings11 of the tube and caused to pass out ward through the nozzleanddischarge end of the tubular extension thereof. The perforated tubeor cylinder also protects the blowpipe from the action of the productsof combustion and tends to keep said blowpipe cool.

Projecting from the inner end of the firebox is a sleeve or hollow boss12, through Which the blowpipe passes, and extending through said sleeveis a bindingscrew 13,

the apparatus or when it is desired to render the-device more compactfor transportation or storage.

The blowpipe 2 is provided at a suitable point between the bellows andfire-box with a T-shaped coupling or union 14, from which a draft-pipe15 leads through the adjacent end of the fire-box intothe bottomthereof, and the object of which is-to enable a current of'air to beforced from the bellows into the bottom of the fire-box for promotingcombustion, especially when starting theapparatus. The draft-pipe isprovided at a suitable point with a cook or controlling-valve 16, bymeans of which when the fire has been properly startedsaid draft-pipemaybe cut off and the full current developed by the bellows caused topass through the blowpipe. The fire box is also provided in its bottomwith a plurality of openings 17 ,formin g a grated S111? face, forenabling the fire to maintain itself after the draft-pipe has been cutofi. The draft-openings in the bottom of the box are covered by means ofa damper 18, having openings 19, similarly arranged and adapted to slidebeneath the bottom of the fire-box. The dam-per is provided with slots20, which work upon headed pins or studs 21 for guiding, s'teadying, andholding in place the damper. The damperis also provided with a suitablefin'ger-grip 22, by means of which it may be turned for opening orclosingthe draftopenings in the bottom of the fire-box. The box is alsoprovided with a suitable cover 23, which preferably has atongue-and-groove sliding engagement therewith and which will tightlyclose the box and prevent the products of combustion from passingtherefrom atjpoints other than the discharge-nozzle.

In operation a fire is built in the fire-box, and any suitablefumigating substance may be used in building the fire or may be added tothe fire after the same is kindled. The fumigating substance may consistof tobaccostems or other material, the fumes of which are obnoxious orfatal to the particular insects upon which the fumes are to be directedAfter the fire has been properly kindled and the cover placed on the boxthe bellows is operated and the draft-pipe left open, so that a currentof air is directed to the bottom of After combustion has been thoroughlypromoted in this Way the cut-off cock is shut, and thereafter the entireblast or current of air is directed through the blowpipe. v By reason ofthe discharge end of the blowpipe being reduced to leave only a verysmall opening the force of the air passing through the reduced end ofthe dischargenozzle is such as to create a suction in the nozzle, whichresults in drawing inward through the perforations of the tube orcylinder within the box the products and fumes and forcing them from thedischarge end of the apparatus against and upon the insects, to thedestruction of the latter.

Any desired form of bellows or other apparatus may be employed todevelop the necessaryblast of air; but it is preferred to use anordinary bellows, and preferably one with a continuous action, as thisenables the apparatus to be manufactured as a portable fumigator and tobe operated entirely by hand. The fire-box may also be of any desiredsize or shape, according to requirements or other conditions,and adischarge tube or pipe of the necessary length may be slipped upon thetubular extension of the nozzle in a manner that will be readilyunderstood without illustration or further description.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described apparatus will be readilyapparent to those skilled in the art without further description, and itwill be understood that various changes in the form, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing anyof the advantages of this invention.
